<p>I’m not sure what I am not seeing for the first one as I’m assuming one, a 90 degree angle</p>

<p>The second 1, let 61 equal the length of the line and substitue the points, not sure how to type up the formula for length of the line here but you would end up w a quadratic equation of y^2 -28y +75 and then solve for y</p>

<p>Uhh, angle ABO can only be 90 degrees. I’m not sure how 3 is correct.</p>

<p>For 2, I find it helpful to memorize some Pythagorean triples. In particular, there is the 11-60-61 triangle. The solution follows immediately.</p>
